Gravothermal solutions of SIDM halos: mapping from constant to velocity-dependent cross section

Posted by klaurent May 5, 2022Peking

Shengqi Yang, Xiaolong Du, Zhichao Carton Zeng, Andrew Benson, Fangzhou Jiang | Summary: [[{“value”:”The scale-free gravothermal fluid formalism has long proved effective in describing the evolution of self-interacting dark matter halos with a constant dark matter particle cross section. However, whether the gravothermal fluid solutions match numerical simulations for velocity-dependent cross-section scenarios remains untested. In […]

Hermitian Nonlinear Wave Mixing Controlled by a PT-Symmetric Phase Transition

Posted by dbos May 5, 2022Cornell

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Noah Flemens, Jeffrey Moses, , , | Summary: While non-Hermitian systems are normally constructed through incoherent coupling to a larger environment, recent works have shown that under certain conditions coherent couplings can be used to similar effect. We show that this new paradigm enables the behavior associated […]

Intrinsic spin Hall torque in a moire Chern magnet

Posted by klaurent May 5, 2022May 17, 2022Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: C. L. Tschirhart, Evgeny Redekop, Lizhong Li, Tingxin Li, Shengwei Jiang | Summary: In spin torque magnetic memories, electrically actuated spin currents are used to switch a magnetic bit. Typically, these require a multilayer geometry including both a free ferromagnetic layer and a second layer providing spin […]

Proximity-Induced Superconductivity in Epitaxial Topological Insulator/Graphene/Gallium Heterostructures

Posted by klaurent May 5, 2022Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Cequn Li, Yi-Fan Zhao, Alexander Vera, Omri Lesser, Hemian Yi | Summary: The introduction of superconductivity to the Dirac surface states of a topological insulator leads to a novel state of matter known as a topological superconductor. A topological superconductor may host Majorana zero modes, the braiding […]

TMEM106B is increased in Multiple Sclerosis plaques, and deletion causes accumulation of lipid after demyelination

Posted by klaurent May 5, 2022May 17, 2022Yale

Kavli Affiliate: Stephen Strittmatter | Authors: Bridget Shafit-Zagardo, Simone Sidoli, James E. Goldman, Juwen C DuBois, John R Corboy, Stephen M. Strittmatter, Hillary Guzik, Sarah Graff and Rashed M Nagra | Summary: During inflammatory, demyelinating diseases such as multiple sclerosis (MS) axonal damage is prevalent early in the disease course. Axonal damage includes swellings, defects […]

The Discovery of a Planetary Companion Interior to Hot Jupiter WASP-132 b

Posted by klaurent May 5, 2022MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Benjamin J. Hord, Knicole D. Colón, Travis A. Berger, Veselin Kostov, Michele L. Silverstein | Summary: Hot Jupiters are generally observed to lack close planetary companions, a trend that has been interpreted as evidence for high-eccentricity migration. We present the discovery and validation of WASP-132 c (TOI-822.02), […]
